Summary : The author describes well preserved and rather complete remains of a horse found in a peat-layer of Post-Gacial age, corresponding to the last accumulation of lœss during the interval between the formation of the Russian « limans » and their separation from the sea. The skull of the described horse resembles that of a Kirghiz-horse, its hind legs – those of the extinct Tarpan (wild horse). The mandible is remarkably high and broad ; a rugosity of the lower margin of the horizontal branch makes it allied with that of asses.
Owing to thèse pecularities, a new species, Equus Khomenkoi nov. sp. is established in honour of the well known paleontologist, prof. J.P. Khomenko, by whom thèse highly interesting remains have been discovered.
